Overview
The TPS61060DRBR is a synchronous boost LED driver IC from Texas Instruments, designed for portable applications. It operates with an input voltage range of 2.7 V to 6 V and delivers a constant output current of 400 mA. The device supports a maximum output voltage of 15 V and functions at a switching frequency of 1 MHz. It features PWM dimming capability and includes internal protection mechanisms. The component is housed in an 8-SON (3x3 mm) package and is rated for operation between -40°C and +85°C.
Feature Summary
- Synchronous boost topology ensures high efficiency for portable LED lighting.
- Integrated PWM dimming control allows for precise brightness adjustment.
- Constant current output maintains stable LED performance across varying conditions.
Applications
- Portable white LED power supplies
- Handheld device backlighting
- Battery-powered LED illumination systems
Procurement Notes
Verify the specific ordering suffix DRBR confirms the tape and reel packaging format containing 3000 units per reel. Ensure compatibility with the required 8-SON footprint during PCB layout. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range to maintain device reliability and electrical specifications.
Selection Notes
Select this component when designing circuits requiring a compact solution for driving up to three white LEDs from a single-cell lithium-ion battery or similar low-voltage source. The 1 MHz switching frequency enables the use of small external inductors and capacitors, reducing overall board space. Ensure the design accounts for the 400 mA switch current limit and thermal dissipation requirements inherent to the SON-8 package.
Part Context
This part belongs to the TPS6106x family of constant current LED drivers. It shares functional similarities with variants like the TPS61060YZFR but differs in package type, utilizing an 8-SON instead of a DSBGA. The family is characterized by its synchronous rectification and integrated digital/PWM dimming interfaces for efficient light management in mobile electronics.
Replacement Considerations
The TPS61060YZFR serves as a pin-compatible alternative within the same series, offering identical electrical characteristics but packaged in an 8-DSBGA format. Designers must verify footprint compatibility when substituting between the SON and DSBGA packages.
